Have you specified interfaces with "listen" command ?
I had a problem as you described and have fixed it by moving a listen
directive with a "floating ip" to the top of the list.
So you can try to specify interfaces you will use for SIP and set a
"virtual ip" at the top of that list.
Kamailio 3.2.0
I am trying to setup kamailio to do the sip trunking. It receive the
sip traffic from customer and then send it to carrier.
I have two NIC interface's assigned with three IP's:
Interface 1: ( Public IP's)
x.x.130.34
x.x.130.36 floating IP
interface 2: (private IP's)
10.10.1.31
.36 is a floating IP assigned by Linux-HA (heartbeat/pacemaker).
I only want to use .36 to receive and send sip traffic.
I uses force_send_socket() to send INVITE with .36 IP. But the ACK
message always want to use .34 IP even the Route header has .36 in it
unless I force it with force_send_socket() .
How can I fix this problem?
See below for the SIP messages: (x.x.128.205 is customer IP,
x.x.129.200 is PSTN gateway IP)
